The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.

In GIS-based network analysis, topological measure of network structure can be considered as one of important factors in the urban transportation analysis. Related to this measure, it is known that the connectivity indices such as alpha index and gamma index, which mean degree of network connectivity and complexity on a graph or a circuit, provide fundamental information. On the other hand, shimbel index is one of GIS-based spatial metrics to characterize degree of network concentration. However, the approach using these quantitative indices has not been widely used in practical level yet. In this study, an application program, in complied as extension, running on ArcView- GIS is implemented and demonstrated case examples using basic layers such as road centerline and administrative boundary. In this approach, geo-spatial imagery can be effectively used to actual applications to determine the analysis zone, which is composed of networks to extract these indices. As the results of the implementation and the case examples, it is notified that alpha and gamma indices as well as shimbel index can be used as referential data or auxiliary information for urban planning and transportation planning.

The internal streets of mixed-use commercial complexes, which are the extension of urban streets, are being changed from a mediating space aiming at movement to a staying-type space according to the change of mixed-use commercial complexes. And they function as a resting place of user with court and plaza, and act as an urban public space, and accommodate an activity arising from the gathering of many people. As a result, a role of new relaxation and community space is played in the center of the city. And the aspect of publicness is brought into relief. Hence, this study is intended to examine the characteristics that the internal streets of mixed-use commercial complexes have, and furthermore, it is intended to show the planning characteristics in the contemporary mixed-use commercial complexes. With regard to the method of research, first, space configuration and role of internal streets was examined according to the change of mixed-use commercial complexes on the basic of precedent research and literature review. And the internal streets of mixed-use commercial complexes were classified into doorway part, traffic line, and open space. And the characteristics of internal streets in the mixed-use commercial complexes through the concept of architectural 'publicness' were derived as accessibility, amenity, perceptibility, openness, connectivity and symbolism. The internal streets of mixed-use commercial complexes should be changed by the space planning to secure continuity with the city on the basis of accessibility and connectivity and to reinforce visual openness in the internal streets in order to improve amenity and perceptibility, accordingly the mixed-use commercial complexes will be also born again as symbolic public space in the city. Variously changing elements to improve publicness very importantly act on the planning of internal streets in the mixed-use commercial complexes, and therefore researches should be continuously carried out.

Development restriction areas (greenbelt areas) of Korea were recognized in 1970 as a means to control urban sprawl and conserve the natural environment. Although there have been some achievements, for a long time many planners and residents have requested a redefining of the green belt due to individual property rights restrictions and urban management problems. In fact, a lot of the greenbelt area is being destroyed by urban development. Therefore, conservation of ecological spaces in the green belt is needed to maintain urban naturalness. In this regard, this study suggests efficient methods to manage the greenbelt through the adoption of a landscape ecological value assessment. The greenbelt of the Seoul Metropolitan Area (SMA) is represented as the case study because there has been mounting pressure to develop the area in Korea. In this study, the assessment of the landscape ecology in the greenbelt area focuses on landscape structure and function. The assessment consists of the following steps: First, patches were derived by NDVI analysis using landsat remote sensing data. Second, characteristics of the patches were quantified by analyzing the landscape structure, such as patch size and shape index. Lastly, the gravity model and least cost path analysis to assess connectivity were applied to evaluate the landscape function in the green belt areas. The assessment result showed that 48.45% of green belt area should be conserved to maintain ecological stability and function. Moreover, major ecological networks were identified near the large patches in the northern and southern areas. However, relative low ecological values were identified in the western part of the green belt area due to the lack of green spaces. Furthermore, some development plans in the green belt were also identified near the conservation area. Based on these results, the restoration needed areas to enhance ecological value in green belt were displayed. This study suggests efficient management of the greenbelt area, which is disappearing as a result of urban development. The area for conservation chosen in this study should be managed carefully in urban planning. Finally, the results of this study can be used in green belt polices and plans for the promotion of ecological naturalness and stability.

In order to prepare a basis for ecological restoration of the Seoul Metropolitan area, ecological diagnoses on soil physico-chemical properties and vegetation structure were carried out. Land use patterns, actual vegetation, and biotope patterns were also investigated based on aerial photograph interpretation and field checks. I formulated landscape elements overlaying those data and evaluated the ecological value of each element. Soil pollution was evaluated by analyzing soil samples collected in each grid on the mesh map, divided by 2km $\times$ 2km intervals. Soil samples were collected in forests or grasslands escaped from direct human interference. Soil pollution evaluated from pH, and SO$_4$, Ca, Mg, and Al contents of soil was more severe in the urban outskirts than in the urban center. Those soil environmental factors showed significant correlation with each other. Vegetation in the urban area was different in species composition from that in suburban areas and showed lower diversity compared with that in the suburban areas. Successional process investigated by population structure of major species also showed a difference. That is, successional trend was normal in suburban areas, but that in urban areas showed a retrogressive pattern. The landscape ecological map of Seoul indicates that the urban center lacks vegetation and greenery space is restricted in urban outskirts. Such an uneven distribution of vegetation has caused a specific urban climate and thereby contributed to aggravation of air and soil pollution, furthermore causing vegetation decline. From this result, it was estimated that such uneven distribution of vegetation functioned as a trigger factor to deteriorate the urban environment. I suggested, therefore, a restoration plan based on landscape ecological principles, which emphasizes connectivity and even distribution of green areas throughout the whole area of the Seoul to solve this complex environmental problem. In this restoration plan, first of all, I decided the priority order for connection of the fragmented greenery spaces based on the distances from the core reserves comprised of green belt and rivers, which play roles as habitats of wildlife as well as for improvement of urban environment. Next, I prepared methods to restore each landscape element included in the paths of green network to be constructed in the future on the bases of such preferential order. Rivers and roads, which hold good connectivity, were chosen as elements to play important roles in constructing green network by linking the fragmented greenery spaces.

This study analyzes the visual access opportunities of neighborhood park users using the Space Syntax theory. In order to achieve this goal, 27 neighborhood parks were selected and 27 axial maps drawn according to the spatial configuration of the sites. Based on the axial map data, this study has calculated some specific space syntax indices, including Connectivity, Integration, and Intelligibility using the Axwoman ver 3.0 based on the Arcview 3.2 application. The value of the representative indices were used to examine visual access opportunities presented by the parks. This study was conducted in two aspects: one focusing on the entire space and another focusing on only the main entrance of the parks. The former used integration and intelligibility values and the latter used connectivity and integration values to evaluate the visual access opportunities of the sites. As a result, this study found that some parks, including Joongang, Balsan, and Sangdang, have high visual access opportunities in terms of the spatial configuration surrounding the park, which shows an integration value higher than 2, and also having intelligibility values higher than 0.7. This is the result of the grid land use pattern surrounding the parks and the straight roads that are closely linked to the main entrances of the parks. It is expected that this methodology and results will be used for locating neighborhood parks during the urban planning stage as providing reasonable evidence.

The design principles of new urbanism (NU) have been adopted for new towns-in town projects for inner city neighborhoods in Seoul, Korea Since 2000. Here, ten NU principles were matched to four urban design categories: streets, land use, housing and buildings, and public open spaces. These elements were analyzed for Eunpyung New Town project. Through the case, the applications and implications NU principles are explored. The principles of connectivity, quality architecture and urban design, increased density, green transportation, sustainability, and quality of life were positively and successively adopted for streets, land use, housing and buildings, and public open spaces. The principles of mixed-use and diversity and traditional neighborhood structure were only partially applied in land use, housing and buildings, and public open spaces. It should be note that the walkability principle is intended not for job-housing proximity, but for pedestrian-friendly street design.

Due to the pandemic caused by Corona 19, cities around the world have faced a change. As the global economic system weakens, localization is increasing in the product production and distribution system. In addition, consumption patterns have changed in urban where localization has been strengthened. As a result, the way physical places are consumed is also changing. Consumption of large multi-use facilities has drastically decreased, the speed of the collapse of the online and offline boundaries has been accelerated, and the consumption of amenities for sharing tastes has become more subdivided, specialized, and private. A big change also appeared in the urban scene, which is perceived as the concentration of urban amenities. Local scale and locality became important in the urban scene, and a new urban scene element called empathy emerged. Empathy aims to connect socially and emotionally to individuals consuming urban amenities. The pursuit of connectivity, taste consumption, and nostalgia. In this study, the space for cultural consumption based on empathy was named as empathetic space and the concept was explained. The importance of empathic space in the urban scene in the future post-corona situation was presented.

The importance of the green space in urban area has been increasing. There are the increasing needs of creation and sustainable management of urban forest. In order to satisfy the need, it is necessary to set indicators for sustainable urban forest. With this regard, this study is to derive the indicators for evaluation of the urban forest through literature reviews, experts opinion, and field survey. The results of the study, the indicators consist of the ecological healthiness, socio-cultural function, and scenic beauty. The ecological healthiness includes stability and naturality (e.g. area, native species, connectivity etc.). The socio-cultural function contain improvement of living environment, stable emotion, community, and environmental education. The scenic beauty includes environmental-friendly facilities, maintenance of urban forest. The indicators have high feasibility to create and manage the urban forest through evaluating urban forest in practical. This indicators are useful to guide to develop urban forest and park.
